[Libosinfo] [osinfo-db-tools PATCH v2 14/16] Move files needed for `make syntax-check` to build-aux

[Fabiano Fidêncio]

Together with the changes, let's adapt GNUmakefile and maint.mk in order
to be able to run those files from build-aux.

GNUmakefile:
- changing both srcdir & top_srcdir, and adjusting the includes of
  cfg.mk and maint.mk were enough to be able to run `make syntax-check`
  from build-aux directory;

maint.mk:
- "ME" variable had to be changed to point to the right place;
- Some paths expecting cfg.mk in the top_srcdir had to be changed;
- tight-scope.mk target dependency has been changed from $(ME) to
  maint.mk;
